Detailed explanation-1: -What were the two original elements in our Universe? Helium (He) and hydrogen (H) being the first two elements created. Studies point to the production of these elements in the first three minutes after the Big Bang. Furthermore, helium and hydrogen make up about 98% of all elements in the Universe (75% H and 23% He).

Detailed explanation-2: -The first elements-hydrogen and helium-couldn’t form until the universe had cooled enough to allow their nuclei to capture electrons (right), about 380, 000 years after the Big Bang.

Detailed explanation-3: -Row one of the periodic table is inhabited by just two elements-hydrogen and helium. These two were among the first elements created during the birth of our universe. They are the source material for the formation of nearly all other elements, and they are the most abundant elements in our universe even today.

Detailed explanation-4: -In the beginning, or at least following the Big Bang more than 14 billion years ago, there was hydrogen, some helium and a little bit of lithium. A grand total of three elements. Today, there are nearly 100 known naturally occurring elements, with hundreds of variants.

Detailed explanation-5: -Hydrogen is the most abundant element in the Universe; helium is second. However, after this, the rank of abundance does not continue to correspond to the atomic number; oxygen has abundance rank 3, but atomic number 8. All others are substantially less common.
